In a large bowl, add lamb cubes, vinegar and enough water to cover. Let soak for at least 5 minutes. Rinse and pat dry, and set aside.
Remove the top and tail of the okra, and slice into ¼-inch thick rings. Do not remove the seeds. Set aside
In a large, heavy based pan, fry the onion and garlic in the oil until they start to brown. Add the lamb and season with salt and pepper. Stir well and cook until the meat starts to brown. Stir in the mixed spices and Noubess Hot Sauce. Stir in the okra and continue cooking for 10 -15 minutes on low heat, until the okra begins to soften. Add the tomatoes and the tomato paste blended with water. You may need to add more water later if necessary.
Stir well, and simmer slowly for about 40 minutes on low heat, or until the meat is tender, the vegetables are cooked and the sauce is a bit thick and creamy. Add the parsley and the lemon juice and adjust the seasoning.
Serve with rice.
Notes
Lamb can be substituted with beef, pork, veal and even chicken.
